I have a retrofit api interface with a method that looks like this:

   @GET("/data")
   suspend fun getData(): DataDto?

The server in this instance is returning a 200, and the json response body is null (bare string, no quotes).

This results in an exception:

java.util.concurrent.ExecutionException: kotlinx.serialization.json.internal.JsonDecodingException: Unexpected JSON token at offset 0: Expected start of the object '{', but had 'n' instead at path: $
JSON input: null

I don’t think I change the backend at this point. Is there any way to get this to work?
